TRACTION-ENGINE.

" Specification of Letters Patent.

Patented July 4, 1916.

Application filed January 18, 1915. Serial No. 2,801.

To all whom it may concem Be it known that 1, WILLIAM H. CAHALL, acitizen of the United States, residing at Racine, in the county ofRacine and State of Wisconsin, have invented a certain new and usefulImprovement in Tractitau-Engines, of which the following is aspecification.

, My invention relates to improvements in traction engines and has forone object to provide means for suspending the traction engine and meansfor mounting upon it the driving shaft in such manner that the suspension and the driving shaft will be free from and unaiiected bychanges in the size of the engine, boiler.

' ,Otherobrjects of my invention will appear from time-to time inthespecification.

My invention, therefore is illustrated more or less diagrammatically-inone form in the accompanying drawings, wherein I Figure l--is a rearelevation; Fig. 2 is a part section with parts omitted and parts brokenaway showing the axle and drive shaft, Fig. 3 is a side elevation withparts in section and parts omitted showing the side of the boiler andthe wing plate pro ect ing therefrom; Fig. 4 is a detail section on anenlar ed scale showing the means for adjusting t e bull shaft; Fig. 5 isa section on the line. 5-5 of Fig. 4.

' Like parts are indicated by like letters throughout the severalfigures.

A is the fire box of a traction engine boiler. A, A are wing platesrigidly attached to the boiler projecting backwardly therefrom on eitherside, They are bent over at the top to attach to the curved top of theboiler as at A a I A is any suitable type of traction engine mounted onthe boiler. It drives a fly wheel A.

A is a pinion rotating with the fly wheel in mesh with the differentialgear A A is a differential housing within the gear A and containing adifferential diagrammatically shown.

A is a bull shaft. It carries at one end the bull pinion A rotatablymounted thereon, at the other end the bull pinion A rigidly mountedthereon. These are in mesh with the bull gears A", A on the driving andsupporting wheels A which wheels are mounted on the axle A one of thewheels being keyed to the axle the other free to ro- .able manner nothere illustrated asit forms no part of my invention. 1

' B is a cannon bearing extending through the two wing plates andenlarged at eitherend to contain bearing sleeves 13*.

B, B are oil buckets from which the bearings may be lubricated throughthe passages B.

B B are slotted arms projecting outwardly from the cannon bearing B oneon either side of the lug B The lug B is rigidly mounted on the boilerand contains a pin B passing through the slotted portion of the arms 13,13 to prevent rotation of the cannon bearing B The location 'of themeans for preventing rotation of the cannon bearing at the center of theboiler prevents longitudinal movement of the can- 30 non bearing withoutinterfering with the relative expansion and contraction of the cannonbearing and the boiler.

C is a substantially semicircular enlargement on the lower side of the.aperture B to permit passage of the arms B when the cannon bearing isplaced in position in the wing v .plates.

C is a saddle located in the aperture C and grooved at' C to engage thewing plates A and to be held in position thereon.

C is an engagement surface on the lower side ofthe cannon bearing B toengage the wedge C which slides upon the upper flat surfaces of thesaddle C and may be forced into position by the nut C on the bolt C tohold the cannon bearing snugly in position and prevent undue vibrationand Without in- E" is a flanged eccentric ring held adjust- I ablewithin the aperture B by means of bolts E This ring surrounds the cannonbearing D which bearing is free to slide within the ring. The rotarymovement of this ring provides a large range of adjust ment of theposition of the cannon bearing D with respect to the wing plates andthus permits of accurately positioning the shaft A with respect to theshaft A to give the proper distance between the gear centers and tocompensate for wear and the like since by withdrawing the bolts E movingthe eccentric ring through a slight distance it is obvious that a largenumber of adjust ments may be obtained.

It will be evident that while I have shown in my drawings an operativedevice, still many changes might 'be made both in size, shape andarrangement of parts without departing from the spirit of my invention,and

' I wish, therefore, that my drawings be regarded as in a sensediagrammatic.

The use and operation of my invention are as follows :The wing platesare riveted to the boiler. The same is true of the two lugs adjacent theupper and lower extremities of the wing plates. The lower cannon bearingis inserted through the hole in one of the wing plates and carried overuntil it passes through the other with the arms on the cannon bearingmounted on either side of the lug of the boiler. The pin is then passedthrough the lug of the boiler and the slots of the arm and theeccentriorings inserted into the openings in the wing plates andsurrounding the cannon bearing so that the cannon bearing is mountedslidably in position in the wing plates and held against rotationtherein. The two-part axle is then inserted into the cannon bearing andthe wheels are mounted thereon. Jacks or other supporting means whichhave heretofore supported the boiler will be released and the boilerwill be allowed to settle so that the weight thereof is carried by thecannon bearing which is supported by the semicircular Babbitt member onthe shaft. The upper cannon bearing is then put into position in thesame manner so that the two arms thereon are one on eitherside of thelug on the boiler and the pin is then put in place to prevent rotation.'The saddle is then put least so far as the purpose of my invention isconcerned. The bearings have been lined up and the bearings are free tomove with respect to the boiler from the anchor at the center so thatthe differential expansion and contraction of the boiler and the hearingwill not be harmful and will not a fiect the boiler in any way.

I claim 1.
